Evan got the title 'Rule Breaker' and with the help of this title he can enter the tower of ascension without reaching S rank.
Evan has very little information about the tower of ascension. He knew if someone clears the tower of ascension they will be able to surpass S rank, and will reach a higher world than Arora world.
In the academic library, there was very little information available about the tower of ascension.
He checked on the internet and also didn't find much information there.
There was some minor information like your race may also evolve after clearing the tower of ascension, but overall he wasn't able to find anything significant about it.
Evan wanted to gather more information about the Tower of ascension so he asked Valery.
Although he wasn't sure he can guess Valerie's backward is not simple, and she might have more information about the tower of ascension.
